Hong "MadLife" Min-gi started playing StarCraft at the age of 7. He found himself enjoying the Aeon of Strife game-type, and so when a friend introduced him to League of Legends in September 2010 he started playing. His first champion was Akali. The first role he favored was AD Carry, but when he began to play professionally he switched to support.
During his career, MadLife has become world-renowned for his exceptional support play, particularly on play-making skillshot-based champions like Thresh and Blitzcrank. He became particularly well-known for aiming hooks in the direction in which he predicted a player would Flash and landing them dead-on.
MadLife's first professional team was MiG Frost, which he joined alongside Woong, CloudTemplar, RapidStar, and Locodoco. The first tournament they participated in was Azubu The Champions Spring 2012 where they played well but ultimately fell in the finals to their sister team MiG Blaze. Locodoco left the team shortly after and Woong became MadLife's new lane partner. Frost and Blaze were both bought by Azubu and participated in Azubu The Champions Summer 2012 under their new organization. Frost ended up reverse sweeping CLG Europe in the finals and qualifying for the Season 2 World Championship. Unfortunately for Frost, they dropped in the finals 3-1 to the Taipei Assassins and took second place.
In the beginning of Season 3, MadLife and Frost attended IEM Season VII - Global Challenge Katowice but lost in the semifinals 2-0 to Gambit Gaming. Not long after OLYMPUS Champions Winter 2012-2013 ended and Frost dropped in the finals 3-0 to NaJin Sword. After Frost attended the IEM Season VII - World Championship and lost 3-1 to Blaze in the finals, Woong left the team and Hermes became MadLife's new AD Carry. MadLife was voted in to attend All-Star Shanghai 2013 where he and his teammates placed first, winning Korea another spot for the Season 3 World Championship. At OLYMPUS Champions Spring 2013 they got swept by Blaze in the semis and by SK Telecom T1 2 in the 3rd place match so Hermes was benched in favor of the sub AD Carry, Space. Frost's next tournament was HOT6iX Champions Summer 2013 where they once again disappointed, placing 4th after being swept by the KT Rolster Bullets and losing in a close 3-2 set to MVP Ozone. MadLife and Frost attended the Season 3 Korea Regional Finals with aspirations to go to worlds but were swept in their 2nd round by the Bullets.
Frost's decline continued as they were knocked out of the quarterfinals of PANDORA.TV Champions Winter 2013-2014 3-0 by Samsung Ozone. Frost qualified for IEM Singapore where they lost in the finals 2-0 to Invictus Gaming. The new year didn't start well for Frost as HOT6iX Champions Spring 2014 saw them lose in the quarterfinals 3-1 to Samsung Blue. Frost failed to make it out of groups for the first time ever at HOT6iX Champions Summer 2014 which caused them to miss the 2014 Season Korea Regional Finals.
CJ Entus was forced to combine the rosters of Blaze and Frost after the changes to the OGN rules but the bot lane pair of MadLife and Space remained unchanged. They were invited to IEM Katowice in March 2015. They finished in 5th/6th place, after defeating Gambit Gaming but then losing to Team SoloMid and Team WE. CJ participated in SBENU Champions Spring 2015 where they lost in the semifinals 3-2 to SK Telecom T1. Max was called up to the starting roster prior to the start of SBENU Champions Summer 2015 to share the starting support position with Madlife. CJ placed third in the regular season of Champions Summer but lost 3-0 to the KOO Tigers in the second round of the playoffs. CJ had enough circuit points to qualify for the 2015 Season Korea Regional Finals but they lost 3-2 to the Jin Air Green Wings.
CJ played in the 2015 LoL KeSPA Cup in November 2015, where they lost 3-0 in the finals to Ever. During the 2016 LCK Spring Season, CJ went 8-10 in sets, finishing in eighth place overall for the spring split.
CJ Entus had a very poor showing in the 2016 LCK Summer Season, going 3-15 total in set score. Madlife was the only player who started every game for CJ, despite the team's frequent use of substitutions in other positions. Despite this, they were locked into tenth place in the LCK season, and CJ Entus participated in the 2017 LCK Spring Promotion. In the first round they were swept 2-0 by Kongdoo Monster, bringing them down to the loser's bracket. There, they beat SBENU Korea 2-0 before falling to ESC Ever in a 3-0 sweep to become relegated from the LCK. This marked the first time an original Kespa team was relegated from the LCK.
